I also talked to DV on another topic and they said they are working on next releases...but it's slow. Mainly due to involved corporations working at an extremely slow pace. I assume covid is still hampering things.I can confirm steelydave's statement that it's just out of stock: in a panic I emailed Dutton yesterday to ask if the Mott SACD was coming back and they responded it should be available again in 2-3 weeks.
Very happy to have received a response, especially with good news!
